Re: Send serial file directly to Fanuc motherboard.
I can't believe that 1100 people have looked at this post. What an active forum.
I have some movement on the machine when I press and hold the EM button. I get a contactor come in and then a servo error 434. On the drive, I get A -> Z drive. Maybe the brake is stuck or not releasing.
However in researching faults, errors etc, I'm wondering if I can reprogram the EPROMS. The ladder logic has been disabled for viewing.
I have a complete set of listings but having the option to view, I’d be in a much better state.
So is the viewing ladder option in the EPROMS or in the diagnostics.
Here are some of the options from the printouts.
R597.1 PAS ENT PASSWORD ENTER
R597.2 PASLDR PASSWORD FOR LADDER DISPLAY
R597.3 LOOSET MACHINE LOCKING SET
R597.4 PASCAN PASSWORD CANCEL FOR TIME OUT
R597.5 LDRENT LADDER ENTER
R597.6 CANENT LOCK CANCEL ENTER
R597.7 LCSETV LOCK SET VALUE
R598.0 LCSET2 LOCK SET VALUE
R598.1 LCSTR1 LOCK START AUX1
R598.2 LCSTR2 LOCK START AUX2
R598.3 LCSTR3 LOCK START PULSE
R598.4 TMOUT1 TIME OUT 1
R598.5 TIMEOU TIME OUT
R598.6 PSCAN PASSWORD CANCEL
I presume the original EPROMS are copy protected. If not whoohoo. I then have to find out how to bypass the diagnostic lock if that is what it is. What software can I use to view and edit the ladder?
Making parts with the machine is great, but getting it to run wakes me up each day. Oh dear I'm an engineering nerd.
